I'm pleased to announce release 2.0 of pam-afs-session.

pam-afs-session is a PAM module intended for use with a Kerberos v5 PAM
module to obtain an AFS PAG and AFS tokens on login.  It puts every new
session in a PAG regardless of whether it was authenticated with Kerberos
and either uses Heimdal's libkafs or runs a configurable external program
to obtain tokens.  It supports using Heimdal's libkafs or OpenAFS's
libkopenafs for the AFS interface and falls back to an internal
implementation if libkafs isn't available.
        
The embedded kafs layer in this version (used if neither libkafs nor
libkopenafs are available) now has untested support for Mac OS X and
Solaris 11.  If you have either of those platforms and are willing to
test, please let me know if it works properly.  You will need to build
--without-libkafs to force use of the embedded kafs code if you have
libkafs or libkopenafs installed.

Changes from previous release:

    If there is no PAG, create a new one and obtain tokens in pam_setcred
    and pam_open_session even if the module has already run.  This works
    around destruction of the PAG on Linux by keyring initialization
    modules, which can otherwise be hard to avoid due to the ordering
    between the auth and session stacks.  This support uses the
    VIOC_GETPAG AFS system call if it is available and falls back on
    analyzing the supplemental group list if it is not.

    Add untested support for the ioctl AFS system call methods on Mac OS X
    and Solaris 11 to the included kafs library, which is used if neither
    libkafs nor libkopenafs is available.

    Avoid returning an uninitialized value from pam_open_session when
    notokens is set.  Thanks, Ian Ward Comfort.

    pam_close_session now removes the module data indicating that tokens
    were already obtained so that opening another session using the same
    PAM handle will work correctly.

    pam-afs-session is now built using Automake and Libtool to bring it
    more in line with other software packages.  This means that it now
    relies on Libtool to know how to generate a loadable module rather
    than hand-configured linker rules.  This may improve portability on
    some platforms and may hurt it on other platforms.

    The symbols exported by the PAM module are now limited to only the
    public API on all platforms where Libtool supports limiting symbol
    exports.

    On Linux, if configured with a prefix of /usr (rather than /usr/local,
    the default), the module will be installed into /lib/security (or
    /lib32/security or /lib64/security if they exist) rather than
    /usr/lib/security to match the default PAM configuration.

    The module is now installed under $libdir/security, rather than a
    lib32 or lib64 directory, except for the special case of /usr.  To
    install into another lib32 or lib64 directory, use the --libdir option
    to configure.

    Fix a configure error when built --without-krb5.

    When debugging is enabled, log an exit status of PAM_IGNORE as ignore
    rather than failure.

    Update the embedded kafs code to rra-c-util 3.0, adding
    --with-libkafs-include, --with-libkafs-lib, --with-afs-include, and
    --with-afs-lib configure options for finer control.  Remove obsolete
    --with-afs-headers configure option (use --with-afs-include instead).

    Add an initial test suite that tests basic functionality and some
    options.

    Update to rra-c-util 3.0:

    * Add --with-krb5-include and --with-krb5-lib configure options.
    * Don't break if the user clobbers CPPFLAGS at build time.
    * Fall back on manual probing if krb5-config results don't work.
    * Suppress error output from krb5-config probes.
    * Search for krb5-config in /usr/kerberos/bin for Red Hat systems.
    * Add support for the old Heimdal krb5_get_error_string interface.
    * Handle the bundled Heimdal on OpenBSD without a separate libroken.
    * Add portability to systems with a broken snprintf or vsnprintf.
    * Update make warnings flags for gcc 4.4.

    Update to C TAP Harness 1.6:

    * Flush standard error before results in the C TAP library.
    * Improve test failure output formatting in some edge cases.
